An egg weighs 20 grams and half an egg How many grams does an egg and a half weigh?

The correct answer is 60 grams.The sentence "An egg weighs 20 grams and half an egg." confuses a lot of people because people mistake it for a compound sentence. Then, they neglect the second part of the first sentence and move onto the question blindly. If it was a compound sentence, then the egg would actually weigh 30 grams, but in this case, it's not.This is what it looks like if you were to write down the first sentence into a math problem:Egg = 20 grams + 1/2 EggorX = 20g + 1/2Xso, subtracting 1/2x from both sides of the equationX - 1/2X = 20 gor1/2X = 20 gsoX = 40 g, the weight of one egg.Now, if I were to say, "An egg weighs 20 grams and also half of its weight." (This is what people get confused with) Then, this is what it would look like.(Egg = 20 grams) = (Egg = 20grams + 1/2Egg)orE = 20gramsG = 20 grams(E = G) = (E = G + 1/2E)Which results to 20 = 20 = 20 = 20 + 10Conclusion:You can't modify a total of something with another number. People read the first part of the first sentence and they make a stopping point before they read the rest of the sentence. Thus, they would assume an egg weighs 20 grams. They think, "Okay, so I know an egg weighs 20 grams." But the sentence is not just saying it weighs 20 grams. It says it weighs 20 grams AND half an egg. If you read it backwards, you would understand. Let's try, "An egg weighs half an egg and 20 grams." Two halves make one. So if you are already given something in two pieces and half of it is given to you first, you will assume the other half is equal. Therefore, half of an egg would be 20 grams. If you're still confuse, pretend I am handing you half an egg and I say, "Hey, here is half an egg. It weighs 20 grams. Can you guess the other half?" Hopefully you would say, "Yeah duhh 20 grams!"Pretty tricky question. English grammar plays an important role in it. Hope this helps.-Hai
